How do you set GDB debug flag with cmake?

I have tried setting the debug flags using the

set

command in cmake but I cam unsure what to add. I have been told things like DEBUG=true but so far i am unable to find the correct flag to set.

Alternatively you can use the CMAKE GUI to make this change. Doing ccmake with the project will yield a screen similar to this:

enter image description here

Entering Debug in the CMAKE_BUILD_TYPE field will allow you to build with debug flags.

If you want to build for debug (including source information, i.e. -g) when compiling, use 

cmake -DCMAKE_BUILD_TYPE=Debug <path>

If you want to build a release build, you can use 

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo <path>
